Does he have any problems in Windows XP? If not, then it is not a 
hardware issue.

I am inclined to think that he either has corrupted files or has been 
rooted. Unfortunately, there is no builtin checksum capability like what 
you get with rpm packages so at this moment, I do not have any 
suggestions on how he can verify that his files are intact.
